They are secure as long as they're stored correctly.

You are right. If you save the private key with private key’s QR code in that. That will not get destroy at any point. Whenever you need just need to import the private in to your wallet. Its very easy to do as well.

Through both exporting and importing, though, if you're on a compromised system, someone can get the private keys. This isn't solving the security aspect at ALL.

Possibilities are, system might not be compromised one if it's an offline one, use it and use your USB stick to save those QR codes in it, then store that USB in a safer place, and you are done...

If you generate the private keys offline, then it should be secure.

not really, there , like it was said the problem with the memory cache of the printer, so you should be sure that nothing is stored there, i'm talking about your private key

It`s strongly recommended to import whole amount of paper wallet when do so. No one can ensure security of Private key once is used. Just import all and you are safe.

I've a few paper wallets that are a few years old. The coins are still sitting there contentedly. Brain wallets just don't do it for me. I'd be worried about my mind going or not creating enough entropy to begin with.

I made a brain wallet that was easy and nobody cracked... they're really more secure than people realize. There's just so many options, they're not WORTH trying to crack.

give me your cryptos

They are basically a private key written on a piece of paper. As long as you make sure no one has access to your private key, you generate, print, then delete the paper wallet offline, and they're have been no pictures or records taken of the paper wallet. Then you'll be safe.

Bitcoin paper wallets have off late become quite a decent solution to store BTC safely Its growing concern for security of bitcoins. paper wallets are completely offline and are safe from online threats such as remote administration tools, Trojans, malware, and botnets. This paper and offline wallet only can the 100% safety for our wallet:)

I don't consider them the most secure, They have the risk of burning or becoming unusable by water etc... still more secure than a direct online wallet in a PC though.

They're secure IF you keep them safe. If you generate them and someone has hacked your PC, it does no good. The SAFEST is a brain wallet. No traces.

When I want to create a paper wallet, I use vanity gen on an offline computer to generate the address and I change the text to QR code using a website which work offline

Thats a good idea, i may get my laptop setup just for this and transfer all my wallets i made online. Do you have a link for something that can convert addresses to QR offline?

thanks

Here is the site that I was talking about.
https://www.the-qrcode-generator.com
It works offline without any problems and I tried it on PC and mobile .
You can also scan qr codes with this site

qrencode for Linux and qrencode-win32 for Windows will do what you want.

Superb, i already have linux installed on my laptop so all i have to do is find a vanity gen that works on linux, or just copy my private and public from my main pc. Anyway fantastic cheers.

Perhaps your distro already has vanitygen as a precompiled package. If not, you can get the source here: https://github.com/samr7/vanitygen

Thanks again, i have kali on it at the moment so its pretty unlikely that there will be a vanity gen on it but its no major dramas to install it or worst case scenario i will just put a different distro on it.
